So with 
Meet Loki!
Loki was a rescue from a local vet, after her prior owners kept her outside because they were allergic, and she got beat up by another cat. They didn't want to pay for surgery, so the vet took her in abd patched her up out of pocket.
The day I met her, she chirped at me through the cage doors and purred loudly when I gave her a pat, so I knew I had to take her home.
That was eight years ago, and now at age 12 (or so), she still acts like a young cat!
